Application filed July 1'7, 1903. Serial No. 166,016- (No specimens.)

To aZZ whom it may concern.-

Be it known that I, EDWARD KAYE, a citi zen of the United States ofAmerica, and a resident of Monaca, in the county of Beaver and State ofPennsylvania, have invented certain new and useful Improvements inMethods of Manufacturing Glassware, of which the following is aspecification.

My invention has relation to the manufacture of glassware, and has forits object the provision of a novel method whereby the number ofarticles produced by a given number of workmen may be made of a qualityequal to regularly-blown ware at a cost not in excess of the cost ofinferior grades of pressed ware.

In carrying my invention into effect I proceed as follows: A quantity ofglass is gathered and manipulated in the usual way and blown into a moldof such shape that the blown glass embodies two or more articles unitedtogether, each such article having a finished part. The blown glass isthen knocked off the blowpipe and while the several articles are stillunited is conveyed to a leer and annealed. The articles are thenseparated by cracking them apart on the line of juncture and placed in asuitable heating-furnace and heated up to a point where they can besafely reheated at a glory-hole, and after they have been there heatedto a suitable degree they are fashioned to thedesired shape.

In the accompanying drawings, Figure 1 is a vertical sectional view of amold adapted to form the articles two at a time in a finished orpartly-finished condition. Fig. 2 is a side view of the articles soproduced before being annealed and cracked off. Fig. 3 is a side view ofthe two articles when cracked apart. Fig. 4 is a vertical sectional viewof a furnace for heating the articles after they have been crackedapart, and Figs. 5 and 6 are side views of forms of articles made fromthe two parts shown in Fig. 3.

A designates the mold, andB the glass which has been blown in the sameto the shape shown by means of the blowpipe C. The two sections 1) E ofthe glass, which are shown in the mold A in one piece, are designed whenseparated to be formed into two lamp-shades, and

the fitter, or that part which is held by the gas-fixture, is formed inits completed shape, as shown at (Z 0 in the mold, while the part E hasa part c, that connects it with the blowpipe, and the part I) has abottom piece d, that is cracked off after the glass has been removedfrom the mold, as will be presently described. After theglass has beenblown in the mold A, which is accomplished in the usual manner, the moldA being either a still-mold or a twistmold the mold is opened and theglass IGlIlOVOCl and knocked off the blow-pipe at the line w :n. Theglass is then conveyed to a leer and properly annealed and after beingannealed cracked off on the lines w "w, y 1 and a, leaving the two partsshown in Fig. 3. It will thus be seen that the cracking-oil operationjust described has left two parts, each of which has a finished fitteror portion adapted to be clasped by the gas-fixture to hold the shade inposition, and these two parts, which now constitute separate andindependent articles, are conveyed to the furnace, (shown in Fi 4D,)where they are heated up to adegree that renders it safe to stillfurther heat them at a glory-hole, at which the edges and as much of thebody as it is desired to fashion to a different shape are heated to therequired degree, when the articles are then worked to any desired form,as by placing them on a crimper or by manipulating them by hand withsuitable tools, after which they are again conveyed to the leer andannealed.

If it be desired to maintain the shape given to the articles in thelirst mold in which they are blown, the unfinished edge which is leftwhen they are cracked 011 on the line w w is merely glazed orlire-finished at the gloryhole after the articles have been reheated, asabove described; but it is obvious that the shape of the article may bevaried to any required degree after they have been heated at theglory-hole, and I have shown in. Figs. 5 and 6 two completed articlesmade from the parts shown in Fig. 3, the one shown in Fig. 5 having beenformed by pressing the glass down on a crimping-block and the other,shown in Fig. 6, having been produced by spreading the glass in themanner well understood by glass-workers.

From the above description it will be seen that the part which is blownin the mold in the first instance is capable of being transformed intotwo differently-shaped articles or into two which are of the same shapeas may be desired. The saving thus effected is not only that of thewages of one blower, but of all of his assistants, and the output of thefactory will be equal, so far as the blowing department is concerned, tothat of a factory employing twice as many hands.

Having described my invention, I claim 1. The method of manufacturingglassware, consisting in blowing a form with two or more finishedportions, then annealing the form, then cracking it off to produce twoor more separate articles, then reheating the articles and forming themto final shape.

2. The method of manufacturing glassware, consisting in blowing a massof glass in a mold to a shape embodying two or more attached articles,then removing the glass from the mold and annealing it, then crackingoff the articles, then simultaneously reheating the separate articlesand then fashioning them to the desired shape and then again annealingthe articles.

3. The method of manufacturing glassware, consisting in blowing a formwith two or more finished portions, then annealing the form, thencracking it off, to produce two or more separate articles, thengradually and simultaneously reheating a plurality of the articles in areheating-furnace and then further heating them severally at aglory-hole and forming them to final shape.
